PASSIVE HYDROGEN FREQUENCY STANDARD Russian patent published in 2017 - IPC G04G3/00 G04F5/14 H01S1/06 H03L7/26 

FIELD: radio engineering, communication.

SUBSTANCE: frequency standard includes a quantum discriminator 1 with a coupling loop 2 of its resonator frequency tuning, a frequency converter 3, an amplitude detector 4, phase shifters 5, 13, synchronous detectors 6, 14, a crystal oscillator 7, a modulator 8, a modulating frequency oscillator 9, a frequency multiplier 10, a generator of harmonics 11, a tunable frequency synthesizer 12, a rectangular pulse oscillator 15 and a digital-to-analog converter 16, the output of which is connected with the coupling loop 2 for frequency tuning of the quantum discriminator resonator 1, and its second input is connected to the synchronous detector output 14 made by the digital and the second input connected to the second output of the rectangular pulse generator 15.

EFFECT: reducing the temperature coefficient of the device frequency and improving the frequency stability of the time averaging 1 per day.
